Time for a complete system overhaul -- Looking for input.

Interesting but are you able to make sure each tank is getting equal flow? Only way i see is using a flow meter, like the caleffi quicksetter series balancing valve.

If the contentions to the tanks were reversed on the top or bottom that would defiantly help the flows

I don't have flow meters. And don't plan on installing any. The tanks are piped in parallel and my feed loop supply is out the right side and the return comes into the left. So the assumption is that they are balanced. I do have thermal wells in each tank so I could measure both tanks independently for temperature high and low. But I would be surprised if there's a significant discrepancy between the tank temperatures.

Be ready to be surprised...

I agree your in for a surprise!

You need reverse piping at the top!
This will balance out the flow over both tanks.

The way you have it piped now, only the tank closest to the boiler will heat up.
Water always takes the easiest path.

Also, there is no anti-condense boiler protection (mixing valve or injection pump)
See location anti-condense mixing valve with setting of at least 160F
